Hopefully this would apply to you where ever you are but it hit my email this morning.

Hi, I recently got the same code.  Did it turn out to be a bad O2 sensor?

Phone volume all the way up?

LOL I did that once too

Parts are on the way for all of that, and when I looked up I believe it was 206 degrees. Impeller was replaced towards the end of last season but have another on the way. Went back and ran the code scan again last night after I got back home with the boat on a fake lake.  I have 8 inactive codes showing. 
 

-oil press spn 100

data valid but below normal range

-crank signal spn 636

data erratic or incorrect

-mhc failure spn 65581

bad intelligent device

-cyl 1 misfire spn 65591

mech system not responding

-etc pps2 range spn 65604

data erratic

-etc pps1 range spn 65605

data erratic

-etc pps1 range spn 65605

bad intelligent device

-etc pps12 correlation spn 65613

data erratic

During the code read the boat ran fine on the fake lake. I’m working today so I won’t have a chance to get it into the water until tomorrow evening to see if it goes into limp again and what codes reoccur.

Does anyone have advice on identifying starting issues with M6Di.  My 2022 Response occasionally fails to start.  The motor turns over and sort of stumbles and fails to fire.  When I hit the starter button again the motor winds over a for a slightly longer period of time and then usually starts.  Sometimes it is like it has flooded and will run rough for a couple of seconds and then be fine.  This happens around one start in thirty and today it was the worst it has ever been.  We waited a few minutes, turned the isolator off and back on and it started first attempt with no issues.  We had skied the course for a couple of hours before this happened and boat was great.  Am trying to determine whether there is a likely fuel pump or advance issue or whether something electrical with the isolator switch or failing battery could be the cause.  I opened the fuel cap today and there was a big suction of air into the tank like it had pressurised as fuel was being used.  When the motor winds over there sounds to be heaps of grunt from the twin batteries.  I am getting the batteries tested tomorrow, just can't help wondering whether this sounds more like a fuel or air cause.  Would definitely appreciate any advice you could share.
